Understand that, unlike the Graham-based value investors, Warren is not saying that Coca-Cola is worth $60 and is trading at $40 a share; therefore it is “undervalued.” What he is saying is that at $6.50 a share, he was being offered a relatively risk-free initial pretax rate of return of 10.7%, which he expected to increase over the next twenty years at an annual rate of approximately 15%. Then he asked himself if that was an attractive investment given the rate of risk and return on other investments.
